Answer: Die is a denotative word and pass away is a connect word
Explanation: This is because die is the literal meaning of pass away so it is denotative.
While, pass away is a connecative word because it is a conjuction of two words, it is used just when we do not want to say a being has died. So pass away will literally mean die.
What we focus on can include body language, which means you can see if someone is upset, or happy, etc. That would help you understand the people around you.
